Research summary

The research investigates statistical methodology for analyzing various types of highly-structured data, such as images, shapes and movies. Since each data item is an `object' in itself then the broad subject area has recently been termed Object Data Analysis. There are challenges due to inherent constraints in the data, which means that we often represent the objects in unusual mathematical spaces. In these spaces a concept of distance between two objects is required and even calculating an average object is not always easy. The project considers methods for analyzing the objects including techniques for prediction and for summarizing important features of the data. Specific applications range from analyzing MEG images of the brain to the tiny scale of studying molecular shapes.
